Planning study news
This study will provide recommendations that address identified safety and multimodal mobility needs on an approximately 11.3-mile stretch of State Route 164 from Dogwood Street East (milepost 2.3) in Auburn to High Point Street (milepost 13.6) in Enumclaw.
Purpose
This study will refresh similar analysis performed by WSDOT in 2009, including updating concepts and recommendations to meet current standards, requirements and current and future needs of the corridor. Its purpose is to produce a corridor vision and implementation plan that meets Complete Street requirements, aligns with local and Tribal plans, and addresses safety and multimodal mobility needs.
This effort will run concurrently with a paving project pre-design between milepost 10.2 to 13.6. More information on this project is forthcoming.
As a planning effort only, this study is designed to identify future improvements and develop an implementation plan for recommended improvements. Travelers should not expect to see construction in the area. The study is scheduled to last thru early 2027 and will include agency and public meetings, events and other engagement with agencies, interested parties and the public.
SR 164 runs along the White River between SR 18 in Auburn, ending at SR 410 in Enumclaw, passing through the Muckleshoot Indian Reservation and areas of unincorporated King County and the cities of Auburn and Enumclaw. It supports connections between these cities and the SR 18 and 167 corridors, as well as the Chinook Pass (SR 410) over the Cascades.
The 2026 study process will refresh a previous WSDOT study conducted in 2009, which recommended numerous intersection improvements and roadway designs along the corridor. The 2026 study will not consider a bypass route between SR 18 and SR 164.
Online Open House
An online open house is open now and available through July 28, in English and Spanish.
Complete Streets
Using WSDOT’s Complete Streets approach, this study will consider multimodal improvements along the corridor, specifically facilities for bicyclists and pedestrians that meet community needs for access and mobility. It will include significant community engagement in order to understand the needs of Tribes, overburdened communities, multimodal users, residents and other interested parties in the area. Recommended improvements will be developed in keeping with WSDOT Complete Streets design standards to provide efficient and integrated designs that address the needs of all modes of travel.
Agency/Partner/Tribal coordination and meetings
A Technical Working Group (TWG) will be set up as part of the study process. The TWG consists of public works, engineering, and planning staff from local, regional, state and tribal entities. The TWG serves in an advisory role to WSDOT providing technical feedback at multiple steps in the study process. Engagement is also planned with executives and leaders from local, regional, state and tribal entities to provide policy guidance.
Community engagement
Community engagement will be conducted throughout the study. Specific engagement opportunities will be shared as the study advances.
